Fitbit Adds Insulin Resistance and Blood Pressure Trends to New Devices, Advancing Non-Invasive Glucose Tracking

Fitbit is rolling out new health features on two of its latest devices that track insulin resistance and blood pressure trends, marking a significant step toward non-invasive glucose monitoring. The features appear on the Fitbit Sense 2 and Fitbit Versa 4, according to the source. Insulin resistance tracking uses heart rate, activity, and sleep data to estimate how the body responds to insulin, while blood pressure trends are derived from pulse arrival time. These additions could help millions of users monitor metabolic health without needles or cuffs. The move positions Fitbit, owned by Google, in a growing market for wearable health tech that competes with Apple and Samsung. For people with prediabetes or hypertension, early warnings could prompt lifestyle changes or medical visits. The source notes that the features are not medical diagnostics but are designed for wellness insights. As wearables inch closer to glucose tracking, regulatory approval remains a key hurdle. The next few years may bring even more advanced sensors to consumer wrists.
